' provem'ents in Oil-Burners,of which the following is a specification.

Our `invention relates to atomizers or burners to be used in connection with the --combustion of petroleum or other liquid or pulverized fuel to produce steam or generate heat for any purpose. It is designed particularly to generate steam for locomotive, stationary, and marine boilers.

Itconsists of a metal conduitvhaving superposed passages, one to convey the fuel and one to convey the steam, compressed air,

gas, or other vapor, or combination of the same, to be used in spraying or spreading the fuel or supplying oxygen vto the fire.

The particular feature of this device is in combining the fuel and' vapor on or above a lip or plane having a surface projecting in front of the combined discharge and in forming the lower/vapor openings in a series of small outwardly diverging perforations made through the front of the steam passage.

In the accompanying 'drawings which show the accepted form of our apparatus: Figure 1 is a vertical, longitudinal section on line 1--1` of Fig. 2. Fig. 2 is a plan viewl with parts removed. Fig. 3' is an end elevation. Fig. 4 is a detail, vertical, lon-- gitudinal sectlon on line 4 4: of Fig. 3.

Fig. 5 is a vertical cross section on liner 5-5 -of Fig. 4( Fig. 6 is a plan View of the nozzleblock. Fig. 7 is a perspective view of the same.

' It is the object of this invention to provide a means for more thoroughly forming a ne spray or fog of the liquid fuel, so as to increase its combustion and heating ef-V ripping orflescape of the fuel in drops which are hotfects, and-to prevent any thus finely sub-divided. A

As shown in the drawings, the conduit A has oil and steam passages 2 and 3, the oil -passage located above thel steam passage, and at the rear end of the conduit each of these passages is screwthreaded or otherwise constructed for the connection, respectively, of an Oil and a-steam supply pipe.

For convenience in connecting this apparatus, the oil passages may have connection .place when once set.

bothat the top and bottom, as shown at 4 and 4, and the stearnconnection maybe made, as shown 1 at 5.v The Ifront .or discharge end of the oil vconduit has a rectangular Opening in the form of a horizontal slit, the greatest length of wliich is horizontal and its transverse depth vertical.-

The upper part of this conduitfis curved downwardly, as shown'at 6, and ,the floor is similarly curved, as shown at 7.

The steam conduit, which extends be- I neath the oil conduit, terminates in a series of line holes which are bored horizontally through lthe front or discharge end.r These holes are in' a horizontal plane and may be made parallel or divergent outwardly and of a ineness such that when the oilV is deliveredvfrom the lip of the oil conduit, it is caught by these sprays of steam and immediately broken into a ine mist or fog which is discharged into the furnace 'in .such a Way as to rise and burn within the furnace and is deflected upwardly and for-A wardly to the flue or other continuationof the heating apparatus. vWe prefer to make this steam conduit with an open slot at the front end, and in thisr slot we it a block 8 having holes formed in it;the,block being secured so as .to remain permanently in This enables us 'to form the steam Openings very conveniently before the block is set in place. `These small passages may be made in any manner to secure uniformity and eXactne'ss, and when .the block is in place theywill be a permanent part of the device.

Inorder to prevent any drip of Oil which may pass out along the sides, supplemental passages 9 may extend closel to the sides 10 of the corrugated'table 11, which operates in unison with the discharge passages', said passages 9 being of larger cross sectional area. The action of the table and the side Walls, which inclose the jets of steam and oil as they pass out, is to coniine the combustible mass and prevent it from diverging,

` and also to give it 'a certain movement as it which the steam passes, carry the oil which is delivered upon and into the passing steam dand the supplemental openings at the sides prevent any drops or undivided oil from passing out. The 'result of this is that the whole mass of fuel is in the form of an ex- 'tremely iine fog or spray which is far more rapidly and completely consumed than v `would otherwisev bev the case. No deposit is oil and steam conduits, the oil conduit havallowed and ractical experience shows that there -is less'll in lace in the use of this burner.

aving thus described our invention, whatwe claimand desire to secure b y Letters Patent is` 1. In an oil atomizer and burner, vparallel 4and removable through the front of the" mouth of the conduit, said block having finely divided independent outletsthroug .which steam ,is 'discharged to receive. the

falling oil and Vdeliver a fine fog or mist.

3. An oil burner comprising an oil con.

duit, a subjacent steam conduit, and an inserted block in the mouth ofthe steam c011- duit having a plurality of passages provided in the bottom wall or said lblock for form` ing a plurality. of outlets with the opposing bottom Wall of the steam conduit on which said block seats.

iability of carbonization tak-,

4, An oil burner comprising an oil `con-l duit and a subja'cent steam conduit having a series of finely divided divergent outlets, Vand end outlets parallellyv related and ncluding-the divergent outlets therebetween.

. 5. An oil burner including a conduit having a transverse straight series of linely divided outlets of which .the end ones are parallel and the intermediate outlets angularly .related thereto.

. 6. An oil burner including a steam couduit Having a transverse series of finely d1- vided outletspf which the end ones are parallel and the intermediate outlets angularly lrelated thereto, said end outlets being of larger cross sectlonal area.

7. An oil burner includin an oillconduit, a subjacent steam con uit having a series of closely related and nely divided unobstructed'outlets, said outlets extending in the same. plane beneath `the oil so 'as to uppersurface in the plane of the bottonfsof the outlets `for arresting the oil flowing 'effect an even4 uniform sheetlike discharge .of the steam, and a table .arranged with its down the partitions between said outlets so A as to cause all the oil to commingle with the issuing jets of steam. In v"testimony whereof we have hereunto set our hands in the presence of two subscribing witnesses.
